[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0023] The utility model provides a technical solution: Figure 1 、 Figure 2 and Figure 4 As shown, in this embodiment, a tensile strength detection device for an adhesive tape includes a base plate 1, and is characterized in that: a tension sensor 2 is fixedly installed on one side of the top outer wall of the base plate 1, and a fixing component 6 is installed on the sensing end of the tension sensor 2, and the fixing component 6 includes a mounting frame 601 to which the sensing end of the tension sensor 2 is fixedly connected, and the top and bottom inner walls of the mounting frame 601 are rotatably connected to the same bidirectional screw rod 602, and both ends of the bidirectional screw rod 602 are threadedly connected to a splint 604, and two limit rods 603 are slidably connected inside the two splints 604, and the two ends of the two limit rods 603 are fixedly connected to the top and bottom inner walls of the mounting frame 601 respectively.

[0024] The outer walls of the ends of the two clamping plates 604 that are close to each other are both configured to be wavy, and the two clamping plates 604 can cooperate with each other and overlap, so that the two clamping plates 604 can ensure a better fixing effect of the tape.

[0025] Place the other end of the tape between the two limiting rings 704, and then use the handle to drive the bidirectional screw rod 602 to rotate between the installation frame 601. The two splints 604 restricted by the two limiting rods 603 can be driven by the bidirectional screw rod 602 to approach each other, and then the two splints 604 can tightly fix the tape, so that the force on one end of the tape is sufficiently uniform.

[0026] like Figure 1 and Figure 3 As shown, two opposite mounting plates 3 are fixedly connected to the other side of the top outer wall of the base plate 1, and the two mounting plates 3 are rotatably connected to the same winding roller 4. A motor 5 is fixedly mounted on the outer wall at one end of one of the mounting plates 3, and the rotating shaft of the motor 5 is coaxially fixed with the winding roller 4, and a limiting component 7 is installed on the outside of the winding roller 4.

[0027] Glue one end of the tape to the outside of the winding roller 4, then fix the other end of the tape, start the motor 5 at one end of the mounting plate 3, and the shaft of the motor 5 drives the winding roller 4 to rotate, and then the stretching experiment can begin.

[0028] like Figure 1 and Figure 3 As shown, the limiting assembly 7 includes a limiting groove 701 on the top outer wall of the base plate 1, and two mounting columns 702 are slidably connected inside the limiting groove 701. The tops of the two mounting columns 702 are fixedly connected to limiting rings 704, and the two limiting rings 704 are slidably sleeved on the outside of the winding roller 4.

[0029] The two mounting posts 702 are threadedly connected to the same bidirectional screw rod 2 703 . The two mounting posts 702 are respectively located outside the threads at both ends of the bidirectional screw rod 2 703 . Both ends of the bidirectional screw rod 2 703 are rotatably connected to the two mounting plates 3 .

[0030] The thread lead angles of the threads at both ends of the bidirectional screw rod 602 are smaller than the equivalent friction angle, and the bidirectional screw rod 602 can be self-locking, so that the positions of the two splints 604 will not change arbitrarily after the adjustment is completed.

[0031] By turning the knob, the bidirectional screw rod 2 703 is driven to rotate between the two mounting plates 3 , and the two mounting posts 702 restricted by the limiting groove 701 , the bidirectional screw rod 2 703 can drive the two mounting posts 702 to move closer to or away from each other, and the position of the limiting ring 704 will also move synchronously with the mounting posts 702 .

[0032] The utility model provides a tensile testing device for adhesive tape, and the specific working principle is as follows:

[0033] When the device is working, first adjust the limit assembly 7 according to the width of the tape so that the two limit rings 704 are exactly on both sides of the tape, and drive the two-way screw rod 703 to rotate between the two mounting plates 3 through the knob. The two mounting posts 702 restricted by the limit groove 701, the two-way screw rod 703 can drive the two mounting posts 702 to move closer to or away from each other, and then the position of the limit ring 704 will also move synchronously with the mounting post 702, and then stick one end of the tape to the outside of the take-up roller 4 with reference to the two limit rings 704, and then put the tape on the roller 4. After the other end of the tape is fixed, start a motor 5 at one end of a mounting plate 3, and the shaft of the motor 5 drives the winding roller 4 to rotate, and the stretching test can be started. The other end of the tape is placed between the two limiting rings 704, and then the handle drives the bidirectional screw rod 602 to rotate between the mounting frame 601. The two splints 604 restricted by the two limiting rods 603 can be driven by the bidirectional screw rod 602 to approach each other, and then the two splints 604 can tightly fix the tape, so that the force on one end of the tape is sufficiently uniform.
